Question

On Windows 7 when I try to use the Explorer icon on system tray I get the following error: "Microsoft Visual C++ Runtime Library Runtime Error! Program: C:\Windows\Explorer.exe R6025 - pure virtual function call" I don't get it everytime when I use
it but at least twice a week it is happening. I do not have another explorer already open either.
